Erik van Rooyen’s love of music has inspired a special player edition of the ECCO M GOLF BIOM® H4, which has design details that look like guitar strings. A South African sunset inspired the design of the outsole, which fades from a red-orange to a blue, and also includes his logo. The special edition has all the same technologies as the regular ECCO M GOLF BIOM® H4, including BIOM® NATURAL MOTION®, an ECCO MTN GRIP outsole and 100 % GORE-TEX waterproof protection. Crafted from durable ECCO Leather GORE-TEX 100 % waterproof protection keeps your foot dry BIOM® NATURAL MOTION® technology brings you closer to the ground using an anatomical last ECCO MTN GRIP outsole provides stability, traction and rotational support through three different sections X-TENSA INVISIBLE TECHNOLOGY for enhanced stability ECCO FLUIDFORM™ Direct Comfort Technology for lightweight comfort and flexibility Technology: GORE-TEX: GORE-TEX is a highly breathable and 100 % waterproof membrane which is exceptionally thin and has over 9 billion pores per square inch. We integrate a GORE-TEX membrane into our uppers before carefully sealing them. Using this technology enables us to create comfortable shoes that are guaranteed to keep your feet dry. BIOM® NATURAL MOTION®: BIOM® NATURAL MOTION® technology is based on the natural shape and movement of the foot. It encourages the muscles and ligaments in your leg and foot to strengthen with every step — making your movements more efficient and smooth, and allowing for a more powerful push-off. BIOM’s key elements are reduced seam construction, an anatomical last which is designed to match the curves of your foot, low-to-the-ground construction, and easy flexibility. These features create an embracing glove-like fit that frees you to move with barefoot ease and efficiency.
